Don't knock the shirt thing. I'm not a superstitious guy by nature, but for various reasons, I had worn that blue collared shirt to a couple shows and I went through a pretty good run: met Billy Squier and had a decent conversation with him, met Gary Barden and had a decent conversation with him, got to sing "I Love It Loud" on stage with Gene Simmons (some of you might know I'm a Kiss fan), and got third row center for Bruce's Broadway show from the box office day of, and so I wear it to most shows. I look ridiculous, but I'm almost never the MOST ridiculous person at the shows I go to so I can sleep at night.
I can't speak for Jerry Only, but maybe it was a bonding thing with his daughter; I can't believe he was mobbed in the crowd (no knock on him at all).
